Spanish I+D+i funding Technical University of Madrid, University Carlos III of Madrid and

University of Alcalá Minimalist Infrastructure for the provision of services in ad-hoc

networks Provision of services in scenarios lacking a fixed communications infrastructure Cooperation of humans and electronic devices (computers, sensors/actors,

robots, intelligent nodes, etc) is paramount. Emergency management in catastrophes

Security

Ad-hoc networks are more vulnerable than wired networks Wireless technology Open and dynamically changing topology Lack of centralized control points

Special risks in emergency-support scenarios Main concerns: key distribution and intrusion detection

Traditional centralized approaches not applicable Need a highly decentralized, autonomous and adaptive solution

Agent-based security framework (confidentiality, authentication...) Agent- based cooperative IDS

IMPROVISA Agents

An ad-hoc semantic network

Agent-based intelligent level to support an ad-hoc semantic network

Devices that form an ad-hoc network (personal devices, car PCs, etc.) need to discover services Water level, free beds at hospital, oxygen, etc.

With one or more UDDIs in the network Distributed service location

With no UDDI Agent context knowledge

IMPROVISA Agents

Multilayer-multipath video distribution

Video images need to be transmitted We will use a multilayer-multipath approach

Video information is divided in layers Not all layers are needed Different layers travel through different paths

Multi-agent systems may be used to support path decision

IMPROVISA Agents

Conclusions

We propose the use of ad-hoc networks, formed by personal devices, car PC’s… and some fixed lines to contact external services (hospital, police headquarters, etc.)

Multi-agent systems will be used to provide most of the main needs of the project Intelligent information routing Security Service discovery Video transmision
